COMBINATION STOP-COCK.

SPECIFICATION forming part of Letters Patent No. 301,748, dated July 8, 1884:.

Application filed'Septeuiber 20, 1883.

To all? whmn. it may concern:

Be itknown that VVEBs'rnn PAR-K, deceased, of the city of Norwich, county of New London, and State of Connecticut, did invent certain new anduseful Improvements in Combination Stop-Cocks, which improvements are set forth and described-in the following specification, reference being hadto the accompanying drawings.

This invention relates to that class of devices commonly known as combination bath or combination basin cocks, from which, owing to their peculiar construction, may be drawn (when properly connected) water of any desired degree of temperature, from cold to hot. i

The immediate object of the inventor-was to produce a combination stopcock which should be extremely simple in its construction, not easily worn out, and which in point of price shall come within the means of all who have occasion to use such a device.

In the several drawings hereunto annexed like letters indicate like parts.

Figure 1 shows said device complete. Fig. 2 is a view, partly in section, exposing the valve through which the hot and cold water passes as it mixes. from the rear side, and shows the method of shutting off both the hot and cold water. Fig. at is a top sectional view through theline a. a in. Fig. 1, showing the valve adjusted for an equal supply of hot and cold water. Fig. 5 is a top sectional view showing the valve opened for hot water only. i Fig. 6 shows the valve closed and the entire supply of water out off.

In the annexed drawings, A represents the section of pipe in which the new valve is formed. Hot and cold water pipes'may be attached at either end by means of any suitable connection. The valve d in this device is constructed in the form of a hollow frustnm of a cone, and adapted to enter the cross-head in the pipe from the under side. This taper form of valve becomes especially valuable when, as the natural result of friction, the valve or valve seat becomes worn.

Instead of requiring thecustomary packing, a suitable screw or nut, h,(which also retains the operating-handle C in place,) may be screwed up until the valve is again rendered water-tight. The valve should fit perfcctly in the valve'seat to insure asatisfactory result.

Fig. 3 is a similar view.

(No model.)

To provide channels through which the watcr from the hot and cold pipes may flow and mix before passing outward through the coneshaped valve above referred to, there is 951 ranged a slot or opening, 0, in the side of said valve. The location of said slot relative to the'valve-seat forms one of the principal features of this invention. To produce the best results the width of said slot should be about one-fourth the diameter of the valve, as shownin Figs-4, 5, and 6. One side of the valve-seat is recessed, as at c, said recess being divided into two equal parts by a ver tical rib, I), which serves to support the valve as it rotates, and also tends to turn the current of water into the hollow valve, from which it finds a convenient exit at the bottom. Supposing that the supply of hot Water enters at the right-hand end of the several figures and the supply of cold water from the left-hand, it is evident that if the valve is rotated to the right hand hot water only can pass through. If turned to the left hand, cold water only can enter. If the handle is turned at right angles with the line of pipe, the valve will occupy the position shown in Fig. 6, and the slot 0 being thus effectually closed by contact with the surrounding valveseat,the whole flow of water is cut oif. N ow, by turning the handle half-way around, the valve is brought into the position shown in Fig. 4, thus providing a direct opening from both the hot and cold water pipes into the hollow valve d. By moving the handle slightly to the right or left hand, a greater or less supply of hot water is admitted and the temperature of the water easily controlled.

What is here claimed,and desired to secure by Letters Patent, is

The combination stop cock herein described, consisting of the body A, having valve-seat formed upon one side, as shown, and upon the other side the vertical rib b, forming recesses e e on each side thereoflthe cone-shaped valve (1, engaging the valveseat and supported by the rib, and the screw h, for

regulating the valve and securing the opera-ting-handle (J, as shown and described.
